Proposed patch attached (compiles, untested as yet).

I've been poking at the FTS problem example recently submitted by
Artur Dabrowski. It contains an index declared like so:
CREATE INDEX idx_keywords_ger ON search_tab
USING gin (to_tsvector('german'::regconfig, keywords));
which can be queried like so
select * from search_tab where
to_
14 matches
